Middle pillar fixing device and shutter device

The present invention is related to B-pillar fixing device and the shutter unit to fix the center post of the sheet Yatta device.

  Hereinafter, the background art will be described. FIG. 7 is a schematic view of a center pillar fixing device according to a conventional embodiment. As shown in FIG. 7, the locking mechanism L is retracted when the locking mechanism L is pressed from above by the pin 111 protruding from the peripheral surface of the rod 104b, and the dropping rod 104 is completely inserted into the engagement hole 103. When the force of the pin 111 is dropped and the force of the pin 111 is removed, the latch bolt 113 is protruded again. The latch catch 113 is provided with an unlocking operator 114 projecting out of the lock case 106. I have. The pin 111 is protruded at the same height as the pin 115 protruded from the rod 104b to elastically compress the spring 107. When the pin 111 is unlocked, the pins 111 and 115 are locked by the elasticity of the spring 107 so that the lock case 106 is closed. The lock lever 106 is pressed against the upper surface of the lock case 106 and functions as a stopper for preventing the dropping rod 104 from coming out of the lock case 106. A spring catch 112 is located between the rods 104a, 104b, and is supported by a pair of brackets 116, 116 fixed to the inner wall of the lock case 106 so as to be slidable left and right. And a spring 117 for urging the portion to advance to a position orthogonal to the rod 104b. At the tip of the latch bolt 113, an inclined surface 118 for converting a vertical force acting from above to a downward force into a horizontal force is formed. The unlocking operator 114 is provided to project from the peripheral surface of the latch bolt 113, penetrates the wall surface of the lock case 106, and protrudes to the front side of the lock case 106. An elongated hole for sliding the unlocking operator 114 left and right is formed in the wall surface of the lock case 106. On the back side of the lock case 106, an angle to be fitted to the lower end of the center pillar is integrally formed.

  First, the lower end of the center post is fitted into the angle of the lock case 106, and the entire apparatus is attached to the center post. In this state, the center pillar is erected on the floor, and the drop rod 104 is pushed down to drop the left and right rods 104a, 104b into the engagement holes of the receiving seats. As a result, the pin 111 projecting from the rod 104b is engaged from above with the inclined surface 118 formed at the tip of the latch bolt 113, and the latch bolt 113 is retracted against the elasticity of the spring 117. When the latch bolt 113 is retracted so as to completely separate from the pin 111, the pin 111 passes through the tip of the latch bolt 113 and further descends, and at the same time, the force of the pin 111 acting on the latch bolt 113 is released. Then, the latch bolt 113 pops out vigorously by the resilience of the spring 117, and at this time, a very loud and clear locking sound of "click" is generated. This makes it possible to easily confirm whether or not the drop lever 104 has been completely pressed down to be in the locked state. That is, when the locking noise does not occur even when the dropping rod 104 is pressed down as much as possible, it can be intuitively and reliably confirmed that dust and dirt are accumulated in the engagement hole of the receiving seat and a complete locking state is not obtained. Since it can be detected, it is possible to prevent an accident in which the center pillar comes off due to poor locking. In order to release the locked state, only the latch bolt 113 is slid in the horizontal direction away from the pin 111 by an unlocking operator 114 protruding from the latch bolt 113, and the entire dropping rod 104 is moved by the spring 107. Is lifted in the unlocking direction f by the elasticity of. The locking mechanism L configured as described above is a very simple one comprising a pin 111 protruding from the rod 104b of the dropping rod 104 and a spring catch 112 protruding from the latch bolt 113 with an unlocking operator 114. (See Patent Document 1).
